Bacteria cause dental disease.
These organisms thrive in a dry, acidic mouth and cause bad breath,
plaque build-up, gingivitis, and weakened teeth. Acids from bacteria
erode tooth enamel which leads to sensitivity, cavities and discoloration.
Mouth Acidity + Dry Mouth = Cavities and Dental Disease
||Enamel is a living membrane
that can be easily softened and demineralized by acids.
Dentists cannot stop enamel damage - only removing the acidity
can prevent damage.
Mouth acidity is measured in the pH of saliva. A pH above 7.0
is a safe, alkaline state. A pH below 7.0, it is acidic. The root
surfaces of teeth can be damaged when acidity drops below 6.5 and
tooth enamel erodes if levels fall to pH 5.5. The longer teeth remain
in acidic saliva, the greater the damage from demineralization.
Yet, when saliva levels are alkaline, teeth can strengthen and repair
through a natural process of tooth remineralization. The longer
the mouth pH remains alkaline, the greater opportunity for teeth
to repair themselves.
Mouth pH can fluctuate for a number of reasons related to diet,
body chemistry and hormones, climate, or mouth dryness. Anything
that causes a drop in the mouth pH to make it acidic or to cause
mouth dryness is a risk factor for dental disease. The greater your
risk for dental disease, the more protection you will need to keep
your teeth safe from damage.
To understand and control mouth acidity, it is useful to test
for saliva pH. You can easily keep the mouth in an alkaline state
by eating xylitol. Xylitol protects teeth from mouth acidity and
helps remineralize and repair them.
pH Testing Kit
Learn how to measure the acidity level in your mouth. Kit contains
15 feet of pH testing paper for approximately 150 uses and instructions
to determine your mouth’s pH level.
|“A whole new way to protect our
teeth.” We tested our salivary pH after a long training
session and found it very acidic. Just a couple of Zellies
put us back into the safe zone. It is a whole new way to
protect our teeth."

Instructions for using pH litmus testing paper
Open the pH litmus testing paper from its foil wrapper and replace
the roll in its plastic container and save the color chart for measurements.
Test your natural pH before you eat
or drink anything
1. Tear off about an inch of the paper from the roll.
2. Spit some saliva into a spoon.
3. Dip the litmus paper into the liquid.
4. Take note of the color that the paper turns
Measure your mouth acidity at different times of the day.

Test your xylitol pH
1. Eat a Zellies mint, Zellies chewing gum or granular
2. Let the “juice” bathe your teeth and “swish” it around.
3. Now spit into a spoon.
4. Dip the litmus paper into the liquid.
5. If the testing paper is colored blue or purple it shows that
you have a safe and alkaline mouth. At this pH level your teeth
will be hardening and harmful bacteria will be reduced.
Xylitol is extracted from natural fruit and vegetable fibers.
Zellies gum, mints or granular xylitol should instantly make your
mouth alkaline. The more acidic your mouth, the more xylitol you
When you bite into a lemon you naturally produce saliva in your
mouth. This is nature’s way to wash away the acidity and protect
your teeth. Without help from saliva the acids in your mouth would
dissolve calcium out of your teeth.
Saliva brings calcium and minerals to the tooth and helps repair
any damage. It takes about 20-30 minutes for nature to dilute and
remove the damaging acids from your mouth. This graph illustrates
how acidity puts your mouth below a safe level but there is natural
recovery over time.
Problems occur if you drink more acid before the mouth has recovered.
Constant sipping can keep the mouth in an acid state for hours and
in this way teeth are damaged. This graph illustrates the way frequent
sipping can keep the mouth at damaging levels.
Damage in a dry mouth
AAnyone with a dry mouth will be at greater risk of tooth damage.
Without saliva there is no natural response to wash away the acids.
People with blocked noses or who breathe through their mouths have
less saliva. Allergies, sinus problems, exercise or even sleep can
put you at risk for acid damage.
Dry mouths offer greater risk of dental damage. While some dry
mouth is permanent, caused by disease or radiation damage, everyone
wakes with a dry mouth following sleeping, when less saliva is produced,
so everyone shares this risk.
